Leviticus 19:15-18 Revised Standard Version (RSV)
15 “You shall do no injustice in judgment; you shall not be partial to the poor or defer to the great, but in righteousness shall you judge your neighbor. 16 You shall not go up and down as a slanderer among your people, and you shall not stand forth against the life[a] of your neighbor: I am the Lord.
17 “You shall not hate your brother in your heart, but you shall reason with your neighbor, lest you bear sin because of him. 18 You shall not take vengeance or bear any grudge against the sons of your own people, but you shall love your neighbor as yourself: I am the Lord.
